Sonya explains that it was only so Nell could be ruled out as a potential donor, but Karl reveals it's not that simple - Nell is a match. Sonya is compelled to tell the family, putting sudden pressure on Nell to donate. Toadie is upset that Sonya acted against his wishes, but Walter seemingly accepts their decision to give the matter more consideration and announces his and Zoe's plans to return to Sydney later that day.

Walter then asks to pick up Nell for a final goodbye, but when Sonya and Toadie return home, Nell is gone - along with Walter and Zoe's bags. Walter has left a note saying sorry and has taken Nell.

Meanwhile, Paul reveals to Steph that he wants his share of the motel back so that he can repair his finances.
